Study Notes
Objective Measurements in Physical Therapy
- Objective measurements are crucial in Physical Therapy for quantifying patient progress and treatment effectiveness.
- Objective assessments are used to evaluate pain, range of motion (ROM), and muscle strength.
- Isokinetic devices and their uses are essential tools in physical therapy.
- Algometers are used for pain assessment, measuring pressure-pain thresholds.
Pain Assessment
- Algometers measure pressure and force to determine a pressure-pain threshold.
- A consistent application rate of manual force is key for reliable results.
- Pressure algometers use manual pressure to evaluate pain sensitivity in deep structures.
- Measurements are typically recorded in kg/cm2.
Range of Motion (ROM) Assessment
- Different types of goniometers are used to measure ROM.
- Universal goniometer is a common type with various shapes and configurations.
- Gravity dependent goniometer (inclinometer) and Pendular goniometer are other types.
- Fluid or bubble goniometers, similar in function to inclinometers.
- Electrogoniometers are used for research due to their accuracy. However, they are often expensive.
- Disadvantages of electrogoniometers include cost and the time needed for proper alignment.
Muscle Strength Assessment
- Muscle strength can be assessed mechanically or instrumentally.
- A cable tensiometer uses two cables attached to a fixed object and a limb segment.
- Strain gauges measure the deformation caused by loads on materials.
- Hand held dynamometer, modified sphygmomanometer, and pinch meter are all used for assessing hand and finger strength.
- The values/readings from the test can be used to track progress for treatment planning in patients following injuries or who exhibit certain chronic conditions.
Isokinetic Dynamometer
- Isokinetic dynamometers measure muscle strength at a constant speed.
- Different components include a chair and a dynamometer, which both should rotate about 360 degrees within the transverse plane and the chair should rotate vertically.
- Muscle strength is measured in several ways, including peak torque, work, and power.
- Isometric exercises, which do not shorten or lengthen muscles.
- Passive mode does not require any voluntary force; velocity is maintained throughout the range of motion.
- Factors such as the patient's age, muscle group, and test protocol can all affect isokinetic measurements.
